The Hurricane season has brought a new level of attention to wind resistance in the 
HVAC Industry. As you know, 2005 ended the worst hurricane season in history. With 
this increased level of awareness, comes a greater need for high wind resistant roof 
mounted equipment. To prevent water infi ltration and building damage, it is critical that 
roof top equipment stay affi xed to the roof. But how do you know which product can 
withstand high winds? Turn to Greenheck Models H-G, H-GB, H-CUE and H-CUBE to 
ensure your exhaust fans stay affi xed to the roof.
Hurricane winds start at 75 mph. At speeds of 150 mph, wind can exert a 61 pound per 
square foot pressure or over 750 pounds of force on a fan and curb. Forceful winds 
were the cause of most hurricane damage, exceeding $124 billion dollars in damage in 
2005.
